You can use autolayout and create constraints between the rows to ensure a fixed spacing between labels, regardless of how many lines the labels could grow to — Ken Toh, Dec 01 '16 at 05:47

You can do it very easily by declaring two labels in Storyboard.

Here are steps.

Drag two UILabels in your viewController and select the first one and set constraints like below image.

Select the second label and add following constraints.

Select both labels and set numberOfLines to zero.

Now u can set text dynamically from code.

How the labels is dynamic in this answer? – User511 Dec 01 '16 at 10:00
Bcoz I am setting numberOfLine to zero and have not set label's height to be fixed. So, it will set automatically as per the content of label. – Krishna Datt Shukla Dec 01 '16 at 10:31
It will automatically set the height of the label not the dynamics labels. – User511 Dec 01 '16 at 11:25
Yes, it will set the height of label. and only this was the question . – Krishna Datt Shukla Dec 01 '16 at 11:30

All you have to do is:

 float x=10.0,y=10.0,height=40;
 float verticalSpace=20.0;


for (int i = 0; i < 10; i++)
 {
    UILabel *label =  [[UILabel alloc] initWithFrame: CGRectMake(x, y,50,height)];
    label.text = @"dummy text";// It could be from array as well if you want to add different text for each label. Eg:  label.text =  [arr objectAtIndex:i];
    [self.view addSubview:label];
    y = y +height+ verticalSpace;

 }
